Multi-Channel Toolkit

This represents Richard Dobson's important research into multi-channel facilities (greater than 2 channels) needed for various types of 'surround' sound. In Release 6 the Toolkit functions are built into the main CDP System, Sound Loom and Soundshaper, but can also be acquired separately as command line tools. The Toolkit is downloaded from Richard's website:


This prototype CDP plug-in is written by Richard Dobson, and the Direct-X version can be downloaded from his website: Reference is also made to Richard's work on an extended pvoc format: 'pvocex', which is part of the background work for these plugins. Richard's home page references several other projects and publications regarding his technical work.

Sound and Music Computing in Schools

Richard (and Archer) have been involved in the 'Computing in Schools' (CAS) programme. Their work seeks to help young people learn to code by creating scripts and materials that link programming and musical structures and have a sonic output. For a look at their ongoing work in this area, see: There is also a download available from this page.

AL-ERWIN Granulation & Algorithmic Package

Written by Rajmil Fischman with the assistance of an Arts and Humanities Research Board (AHRB) grant, this is a highly featured software combo with a sophisticated graphic user interface, including both granular synthesis and algorithmic mixing. A fully working version can be downloaded from Also see our information page about this software. Please note that this software is still supplied with CDP Systems, as well as via the above link to Rajmil's website page.

Clouds Granulation Software

This is another contribution written by Rajmil Fischman. Clouds implements a multi-platform real-time asynchronous granular synthesis created with MAX. It can record a variety of sources, including synthesised waveforms, microphone capture and /or audio files. Output formats include mono, stereo, 5.1 surround, octophonic and audio files in a variety of formats. Parameters can be handled graphically or via text files containing breakpoint values.

Tabula Vigilans ('T-V'), by Richard Orton

The availability of this software as a free download has been held up by Archer's move to Plymouth. However, if you would like a copy of the current version, please email him (

Tabula Vigilans (i.e., 'Vigilant Table') is an advanced algorithmic composition language with a clear syntax and a handy range of built-in musical functions. It was originally designed as a real-time MIDI instrument that can play back pre-programmed or instantly generated music under mouse or keyboard control.

It may be useful to look on Tabula Vigilans as an algorithmic score processor. It can define and replay music of a conventional melodic and harmonic nature to envelope-shaped multi-event textures with random features. It was not originally designed to create or shape sounds, but this is now possible thanks to a new function written by John Ffitch which enables calls to CDP command line programs. It can also create and output text files, such as breakpoint files or other file types used by CDP programs. This opens a pathway for a wide range of scripting possibilities including the algorithmic handling of CDP sound transformation facilities.

Archer is working on a complete Tutorial Reference Manual based on Richard Orton's legacy scripts as a step towards the further use and development of Tabula Vigilans. Watch for updates!

Compose with Sounds

CDP member Leigh Landy has been busy with his team of researchers at DeMontfort University creating software (free download) and tutorial materials for composing with sounds. This tremendous resource covers all major areas and are designed for those new to the field, whether young or old. Note the breadth of the following topics to which there are links on their Website:
  • CREATE: Compose with Sounds, Composer Case Studies, Composition Tutorials
  • LEARN: Discovering Music all around us, Properties of Sounds, Organising Sounds, The Science of Sounds
  • LISTENING: Listening Training, Listening Room
  • Encylopaedia


One of the world's leading software synthesis 'engines', Csound is coming of age with a rapid expansion of its internal facilities (some from CDP!) and the advent of new graphic environments. See Dennis Miller's comprehensive article on in Electronic Musician: Csound: It's Not Just for Techies Anymore (Vol 18, No. 8, July 2002).

Also see the tutorial texts edited by Richard Boulanger; these are listed on our Publications page.

Mention was made on our News Page of Steven Yi's Blue, a well-designed graphic front end for Csound, with graphic orchestra editor and time-line score assembler. See the Kunstmusik site for more information.
